The self-reported version of pycryptopp at master@HEAD is 0.7.1.4.182880377279460454774209806269619214747373856330.post4 {{{ >>> from packaging.version import Version >>> release = Version(""0.7.1.869544967005693312591928092448767568728501330214"") >>> head = Version(""0.7.1.4.182880377279460454774209806269619214747373856330.post4"") >>> versions = [release, head] >>> versions.sort() ] >>> versions == [head, release] True >>> }}} The actually newer code has a version that marks it as being older. Perhaps this only affects postX versions but that's sufficient to break testing environments where it becomes difficult to get an in-development version of pycryptopp instead of the last release.
